How do I set DirectX to render?
There are two ways to set DirectX as your rendering engine. In the Preferences window (Window > Settings/Preferences > Preferences), select the Display category. Set the Rendering engine to DirectX 11. Important: To use the DirectX rendering engine, you must use Windows 64-bit and a DirectX 11 compatible graphics card.
What is rendering in DirectX?
Windows Mixed Reality is built on DirectX to produce rich, 3D graphical experiences for users. The rendering abstraction sits just above DirectX, which lets apps reason about the position and orientation of holographic scene observers predicted by the system.
How do you know if I have DirectX?
To check which version of DirectX is on your PC using the DirectX Diagnostic Tool, select the Start button and type dxdiag in the search box, then press Enter. In the DirectX Diagnostic Tool, select the System tab, then check the DirectX version number under System Information.
What is the difference between DirectX and OpenGL?
DirectX supports sound, music, input, networking, and multimedia. On the other hand, OpenGL is strictly a graphics API. One major difference is that OpenGL is cross-platform, and DirectX is available only on Windows and XBox. If you need to develop for more than Windows, OpenGL is the way to go.
Is GDI hardware accelerated?
GDI is hardware accelerated on Windows XP, and accelerated on Windows 7 when the Desktop Window Manager is running and a WDDM 1.1 driver is in use. Direct2D is hardware accelerated on almost any WDDM driver and whether or not DWM is in use. On Vista, GDI will always render on the CPU.
Which is the render to texture class in DirectX 11?
RenderTextureClass is the new class that encapsulates the DirectX 11 render to texture capabilities. DebugWindowClass is the BitmapClass from the 2D rendering tutorials renamed, however it no longer has a texture since we will pass it the render to texture to use instead.
What can you do with render to texture?
The list of things you can do with render to texture is endless and is the reason why it is one of the most powerful tools in DirectX 11. However you will notice that render to texture is very expensive as you are now rendering your scene multiple times instead of just once.
How does a function create a render target?
The function creates a render target texture by first setting up the description of the texture and then creating that texture. It then uses that texture to setup a render target view so that the texture can be drawn to as a render target.
What is debugwindowclass in render to texture?
DebugWindowClass is the BitmapClass from the 2D rendering tutorials renamed, however it no longer has a texture since we will pass it the render to texture to use instead. I call it DebugWindowClass since I usually have a couple of them on screen to help me debug new shaders or multipass effects I am working on that require render to texture.
